Plane processing tooling for marine azimuth thrusters

Abstract

The invention relates to a marine all-direction propeller plane machining tool. The tool comprises a seat frame, a bearing outer casing, bearing packs, a rotating shaft, a power device, connecting pieces, cutter feeding arms and cutters, wherein the bearing packs are distributed at two ends in the through hole of the bearing outer casing; the rotating shaft is arranged in the bearing outer casing through bearing sets; the outer wall of the bearing outer casing is sleeved with the seat frame; and the seat frame is fixed on the outer wall of the bearing outer casing; the lower end of the rotating shaft is connected with the power device; the connecting piece for connecting and fixing the power device and the seat frame are arranged between the power device and the seat frame; the cutter feeding arms are connected with the upper part of the rotating shaft; the cutters are arranged at the outer ends of the cutter feeding arms; each bearing pack comprises a four-point contact ball bearing, a deep-groove ball bearing and a planar thrust ball bearing, which are arranged in sequence form the outside to the inside. The tool has the advantages that the cutter stroke is long, the equipment machining time is saved, the machining efficiency is improved, and the manufacturing cost is low (one fifth to one sixth of the sale prices of domestic like products); the structure is simple and reasonable; the tool can be disassembled and assembled quickly according to practical work environment.

Description

technical field [0001] The invention relates to a marine component processing device, in particular to a marine full-rotation thruster plane processing tool. Background technique [0002] The marine azimuth propeller has the characteristics of large thrust, high propulsion efficiency, low vibration and low noise. Therefore, it has broad application prospects in tugboats and harbor operation ships. This kind of marine azimuth propeller is used in the 75M drilling platform supply tugboat being built by Fujian Southeast Shipyard. [0003] The supply tugboat for the 75M drilling platform is the first type of ship built by the Southeast Shipyard in Fujian Province. In the plane processing of the base of the marine azimuth propeller, there is a problem that the original processing equipment takes a long time and the construction period cannot be guaranteed. Processing tooling, the price of a tooling is about 580,000 yuan, so the company will face the problem of high equipment co...

Problems solved by technology

[0003] The supply tugboat for the 75M drilling platform is the first type of ship built by the Southeast Shipyard in Fujian Province. In the plane processing of the base of the marine azimuth propeller, there is a problem that the original processing equipment takes a long time and the construction period cannot be guaranteed. Processing tooling, the price of a tooling is about 580,000 yuan, so the company will face the problem of high equipment cost. If it entrusts other manufacturers, it will also face the situation of long processing time and unguaranteed construction period. Therefore, it is urgent to design the processing equipment Manufactured to facilitate the smooth construction of the 75M rig supply tug
